What is the reason for water leakage from the exhaust pipe muffler box?

[Nevaeh]

Exhaust pipe muffler box water leakage is caused by incomplete combustion of gasoline. Main components of gasoline: C4-C12 hydrocarbons, belonging to mixed hydrocarbon substances with relatively complex composition. Gasoline combustion changes: Gasoline combustion mainly produces carbon dioxide, water and a small amount of carbon monoxide. The carbon monoxide in the exhaust gas reacts with oxygen again in the three-way catalytic converter to form non-toxic carbon dioxide before being discharged. Formation of liquid water: When the engine is running, the gas discharged from the cylinders reaches 400-800 degrees Celsius or even higher. At this time, the water generated by combustion is in a gaseous state.
